After copy&pasting formatted text (from a browser window, OpenOffice or similar) into the composer, its font size can not be altered.

First I thought it happened randomly, but in fact it seems to depend whether or not the text has "standard" formatting or is e.g. a "heading" (html <h3> for example) in the original document.

Reproducible: Always

Steps to Reproduce:
1) Compose a new mail

2) Go to a web page that has normal text and headings.

3) Select text from header text and "normal" text (I chose two lines of the the bug report form: "Step 2 of 3 - give information" and following line.)

4) Copy it via Ctrl+C / Ctrl+V or simply via the mouse middle click into the composer window.

5) Select the whole text or parts of it.

6) Try to change the font size to "6" or so.

Actual Results:  
The font size stays the same for the part of the test that was "heading" in the former document.
The font size of the formerly "normal" text is changed as requested.


Expected Results:  
All marked text elements should change their size to the requested value.

Other formatting attributes (bold, underline, italic, color, ...)　are changed as requested.

Using the rubber does /not/ reset the font size, but all other format attributes.
